SANITARY TOILET SEAT.

Application filed April 27, 1927. Serial No. 186,920.

This invention relates to sanitary apparatus and more particularly to sanitary covers for toilet seats.

An object ofv the present invention is to provide a pliant apertured covering sheet of suitable material adapted to be placed over a toilet. seat for the purpose of increasing sanitation.

Another object of the invention is to provide means for readily receivin a supply of the. seat covering material an. to provide means for successively issuing a fresh sheet part as required.

Another object isxto provide a combined seat and dual stock containers so connected to the seat as to facilitate the entry of a fresh supply and the removal of the used covers from time to time. In this connection an object is to provide a combined seat and receiving means enabling the concurrent lifting of the seat so that the bowl may be cleansed when desired without interference and without removal of any of the parts.

A further object is to provide a coin or token controlled means for the sheet advancing means.

In carrying out the objects of the present invention one form of means is here shown and other objects, advantages andfeatures will be made manifest in the following specification of the illustrated embodiment; it being understood that modifications, variations and adaptions may be resorted to within the spirit, scope and principle of the invention as hereinafter claimed.

A bowlB is shown as having a top cover C hinged at H to afixed part A-allowing the cover C to be tipped up. The present cover is provided with parallel straight side edges C smoothly rounded so as to permit a cover sheet S to be drawn from its roll R in a chamber 2 over the top of the seat and into a receiver 3, which chamber and receiver are of semicylindrical form to correspond to the fresh roll R, all of which is designed to be wound from across the seat to the receiver 3. The sheet S is provided with spaced holes D to register with the seat aperture and one edge of the sheet S has a series of stop perforations S at distances equal to the pitch of the large seat holes D. a

The chamber 2 has a front cheek 2 and a rear check 2 and a side wall 2, the inner side of the chamber being open from the bottom up so that it can hang close in under the bowl B. The upper ends of the cheeks 2 have alined pivot pins 4 in the front and back corners of the seat G and the top edge of the side walls 2 is rounded in over the side edge C of the seat so that the chamher 2 can be swung outwardly as shown in the dotted lines in Fig. 3, to allow a fresh roll R of paper to be dropped into the chamber 2. The front end of the chamber 2 has a trunnion 5 to enter a recess in the roll spool'F and the rear wall 2 of the chamber has a spring latch 6 adapted to enter the near end of the spool F, so that the latter is turnably supported in the chamber to allow the sheet to be drawn from the spool F.

The receiving chamber 3 has a front cheek 3 and a rear check 3" and a side wall 3, the front and rear cheeks having pivots 7 in the corners of the seat C so as to allow the receiver 3 to be swung outwardly and upchamber 2 and the receiver 3 will hang in close to the bottom of the bowl. It will be seen that the chamber 2' and the receiver 3 are carried by the hingedly mounted seat C and can be lifted up therewith to clear the bowl. Means are provided for advancin the sheet C step by step across the seat 6 to register fresh zones of paper over the seat and such means is here shown as including a winding pinion 10, Fig. 5, having a trunn'ion 11 and dogs 12 designed to interlock in a cross slot F, provided in either or both ends of each spool F, so that one end of the spool in the receiver 3 is positively coupled to a winding pinion 10 while the opposite end of the spool in the receiver 3 is mounted on a spring latch 13. The pinion 10 is engaged by an intermediate gear 14 and this engages another intermediate gear 15 which has a bevel gear face 16 meshing with a master gear 17 lyingt along the side wall 3 and having a sha 18 extendlng therethrough into a gear box 19. I

' Fixed on the shaft 18 is a ratchet wheel 20 and this is en a ed by a double action pawl 21, Fig. 7, whic is mounted on a hand lever 22 which is loosely mounted on the shaft 18. The handle 22 extends above the ear box 19 to be easily pulled forward by fiend and automatically returned by a spring 23.

It is desirable to provide for the uniform advance of the paper S, so that holes D can be successively registered over the seat C, irrespective of the building up of the roll on the spool F in the receiver 3. Therefore, the master gear 17 is so pro ortioned to the winding pinion 10.that t is latter will turn the spool F when it is empty a sufiicient degree to wind the sheet a full pitch from one hole D to the next and from one aperture S to the next. It is obvious that as the roll builds u it will not be necessary to turn the spool in the same amount as when it is empty.

The feed control means includes a lever 25, Fig. 7, pivoted at 26 and having a roller 27 ositioned to register with the line of per orations S in the sheet S. iVhen a perforation moves under the roller 27 this is allowed to move cam 28 against the arm 29 of a lever pivoted at 30 and having an arm 31 bearing against an eye or ring 32. This eye surrounds shaft 18 loosely and is pivoted at 32 on the lever 22 and has a yoke 33 engaging a lever 34, pivoted on the lever 22. The lever 34 in its normal position engages the near end of the feed pawl 21 which is carried by the lever 22.

In operation, when the lever 22 is pulled forward the control lever 34 locks the pawl 21 in one direction and this engages the ratchet wheel 20 and turns it in such a direction as to cause the pinion 10 to turn the spool F and wind the sheet S thereon until a perforation S passes under the roller 27 whereupon the roller shifts forward and the cam 28 presses a ainst the arm 29 of the control lever and tie arm 31 presses the eye 32 eccentrically from shaft 18 with the result that the yoke 32 rocks the lock lever 34 to release the pawl 21 from its control and allowing the pawl to oscillate without acting on the ratchet wheel 20. This, therefore, clears the hand lever from the ratchet wheel when a hole D registers with the seat C; this being an automatic release action. Then when the handle 22 is released its spring 23 pulls the handle backward to normal position during which movement the pawl 21 will click free.

In order to reset the trip lever 25 and allow the eye 32 to come back to center around the shaft 18 the lever 22 is caused to engage a finger 35 of a rock-shaft 36 having a stud 37 on its lower end to engage an extension from the cam 28 if the roller 27 is lying in a stop perforation S. When the cam is lifted by the stud 37 the trip lever 29 is released and allows the eye 32 to come to center under the action of a light spring 38 acting against the trip lever 34. When the trip lever is in effective position it will again engage the feed pawl just as soon as the handle 22 is pulled forward.

When desired, the feed mechanism just above described can bemade effective only by the introduction of a token 0r coin as T, Fig. 9, which is drop ed into the stock of the handle 22 and fal s to a latch lever 40 mounted on the handle 22. In the absence of a token the latch will engage a tooth 41 in a segment 42 concentric to the shaft 18: The weight of the token is sufiicient to unlock the latch 40. As the released hand lever 22 is pulled forward the token T will come into register with an ejection recess 43 in the flange of the segment 42 and a spring 44 in the lever 22 will eject the token sidewise from the lever to the recess 43.

whence it will ultimately fall to the coin box 45.

What is claimed is:

1. The combination with a toilet seat, of a pair of vertical sheet chambers pivotally suspended from the opposite sides of the seat; said chambers being open at their inner sides and having roll pockets at the bottom swinging in under the toilet bowl; one swinging pocket having a winding means to draw the. sheet over the seat from the other chamber and having a gear box lying along its outer side, and said winding means including a feed mechanism in said box and a hand lever therefor extending above the gear box and oscillating between the front and rear ends of the gear box.

2. The combination with a toilet seat and its bowl, of roll receiving means including roll supports constructed and arranged to hold sheet'rolls substantially within the side lines of the 'seat and pivots on the seat whereby the supports are swingably suspended under the bulge of the bowl said supports being free on the pivots and normally swinging inward to bring the rolls under the bowl.

'3'. The combination with a toilet seat and its bowl, of roll receiving means including roll chambers constructed and arranged to hold sheet rolls substantially within the side lines of the seat and having inner open sides to embrace the bowl; said seat having parallel side edges forming guides for the sheet passing from support to support, one of the chambers provided with a winding gear box at one side and a handle at the top of the box and movable forward and rearward along the seat to draw the sheet over.

4. The combination with a toilet seat and its bowl, of roll receiving means including rollsupports constructed and arranged to hold sheet rolls substantially within the side lines of the seat; said supports being pivot ally suspended from the sides of the seat so as to swing out from the bowl for loading and unloading said supports including openside chambers having end cheeks extending up to front and rear edges of the seat and having pivots therein so positioned as to suspend the chambers under the side bulge of the bowl.

5. The combination with a toilet seat of a pair of roll chambers pivotally suspended from opposite edges of the seat and having open inner sides to receive the bulge of a toilet bowl and for loading and unloading sheet rolls when the chambers are swung out.
